File upload

A custom file upload input, without JavaScript

The file element is a simple interactive label that wraps an <input type="file">. It comprises several sub-elements:

  • file the main container
    • file-label the actual interactive and clickable part of the element
      • file-input the native file input, hidden for styling purposes
      • file-cta the upload call-to-action
        • file-icon an optional upload icon
        • file-label the "Choose a file…" text
      • file-name a container for the chosen file name

示例

HTML 

<div class="file">
  <label class="file-label">
    <input class="file-input" type="file" name="resume">
    <span class="file-cta">
      <span class="file-icon">
        <i class="fas fa-upload"></i>
      </span>
      <span class="file-label">
        Choose a file…
      </span>
    </span>
  </label>
</div>

Modifiers #

With the has-name modifier combined with the file-name element, you can add a placeholder for the selected file name. 

<div class="file has-name">
  <label class="file-label">
    <input class="file-input" type="file" name="resume">
    <span class="file-cta">
      <span class="file-icon">
        <i class="fas fa-upload"></i>
      </span>
      <span class="file-label">
        Choose a file…
      </span>
    </span>
    <span class="file-name">
      Screen Shot 2017-07-29 at 15.54.25.png
    </span>
  </label>
</div>

You can move the CTA to the right side with the is-right modifier. 

<div class="file has-name is-right">
  <label class="file-label">
    <input class="file-input" type="file" name="resume">
    <span class="file-cta">
      <span class="file-icon">
        <i class="fas fa-upload"></i>
      </span>
      <span class="file-label">
        Choose a file…
      </span>
    </span>
    <span class="file-name">
      Screen Shot 2017-07-29 at 15.54.25.png
    </span>
  </label>
</div>

You can also expand the name to fill up the space with the is-fullwidth modifier. 

<div class="file has-name is-fullwidth">
  <label class="file-label">
    <input class="file-input" type="file" name="resume">
    <span class="file-cta">
      <span class="file-icon">
        <i class="fas fa-upload"></i>
      </span>
      <span class="file-label">
        Choose a file…
      </span>
    </span>
    <span class="file-name">
      Screen Shot 2017-07-29 at 15.54.25.png
    </span>
  </label>
</div>

You can have a boxed block with the is-boxed modifier. 

<div class="file is-boxed">
  <label class="file-label">
    <input class="file-input" type="file" name="resume">
    <span class="file-cta">
      <span class="file-icon">
        <i class="fas fa-upload"></i>
      </span>
      <span class="file-label">
        Choose a file…
      </span>
    </span>
  </label>
</div>

You can combine has-name and is-boxed. 

<div class="file has-name is-boxed">
  <label class="file-label">
    <input class="file-input" type="file" name="resume">
    <span class="file-cta">
      <span class="file-icon">
        <i class="fas fa-upload"></i>
      </span>
      <span class="file-label">
        Choose a file…
      </span>
    </span>
    <span class="file-name">
      Screen Shot 2017-07-29 at 15.54.25.png
    </span>
  </label>
</div>

You can align the file input:

  • to the center with the is-centered modifier
  • to the right with the is-right modifier

示例

HTML 

<div class="file is-centered is-boxed is-success has-name">
  <label class="file-label">
    <input class="file-input" type="file" name="resume">
    <span class="file-cta">

JavaScript #

A file upload input requires JavaScript to retrieve the selected file name. Here is an example of how this could be done:

示例

HTML 

<div id="file-js-example" class="file has-name">
  <label class="file-label">
    <input class="file-input" type="file" name="resume">
    <span class="file-cta">
      <span class="file-icon">
        <i class="fas fa-upload"></i>
      </span>
      <span class="file-label">
        Choose a file…
      </span>
    </span>
    <span class="file-name">
      No file uploaded
    </span>
  </label>
</div>

<script>
  const fileInput = document.querySelector('#file-js-example input[type=file]');
  fileInput.onchange = () => {
    if (fileInput.files.length > 0) {
      const fileName = document.querySelector('#file-js-example .file-name');
      fileName.textContent = fileInput.files[0].name;
    }
  }
</script>
